Installed Apps entry not updated

When pushing updates to an application installed using QtIFW, the entry in the "Installed Apps" still has details pertaining to the previous update.

Method to Reproduce
1. Inspect "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall{GUID}
1. Provide an update with a new version or name, using .rcc
2. Update installation using `maintenancetool.exe update --accept-messages --confirm-command`
3. No changes to "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall{GUID}

Candidate Fix
In packagemanagercore_p.cpp:1676

        if (m_core->isInstaller() || m_core->isUpdater())
            registerMaintenanceTool();
